[e]. This is a front vowel， which for me ， means it feels like it
comes more from here， eh ， than from here ， ah ， father. To make this
sound ， my tongue comes up ， but not too much because this does not
touch the roof of the mouth. This stays wide， almost flat-feeling， even
though it does come up. The tip of my tongue is not touching the back
of my teeth ， but actually below that， in the soft tissue. It presses
lightly against the front there. Eh ， eh. As you can see ， my jaw drops
some， but my lips do not move， they stay relaxed. [e] 是一个前元音，
对我来说，它就好像是从这里（视频中所指的位置）而不是像ah， father 那样
从这里（喉咙处）发出来。发这个音时，我的舌头抬起，但不会抬得太多，因为
舌根不碰到上颚。尽管舌根抬起，但是它还是保持平展，感觉几乎是平的。舌尖
不触及齿背，事实上是放在牙齿下方柔软的地方，轻轻挤压。Eh， eh.你可以看
到，我的下巴略微向下移动，但嘴唇是不动的，嘴唇保持放松的状态。
